What is the primary reason for rotating rescuers during CPR?

Rotating rescuers during CPR primarily serves the purpose of preventing fatigue and maintaining effective compressions. When performing CPR, the quality of chest compressions is crucial for the effectiveness of the resuscitation effort. Compressions must be performed at an adequate rate and depth consistently to promote blood flow and oxygen delivery to vital organs.

Fatigue can set in quickly, particularly in high-stress situations, leading to a decrease in the quality of compressions over time. By rotating rescuers regularly, the team can ensure that fresh and alert rescuers are delivering compressions, allowing for sustained effectiveness during the entire duration of the resuscitation effort. Regular rotation helps manage the physical demands of CPR, maximizing the chances of successful resuscitation.
